The unit may only be installed and operated in
rooms, when the air rate fed to the unit is sufficient for combustion.
Make sure to install mobile liquid gas reservoir on a
solid ground and in a vertical position.
Liquid gas reservoir may never be used in a lying po-
sition while the unit is operating.
Explosion hazard: Gas exit in the liquid phase from the gas nozzle.
The unit may be operated only in well aerated rooms. Persons may not stay permanently in the room
where the unit has been installed.
Relevant prohibition signs are to be fastened to the entrances.
The unit is to be installed and operated on a solid
non combustible ground.
It is to be ensured that no combustible objects/
materials can be sucked in.
The unit may not be installed or operated in inflam-
mable and explosive surroundings.
A safety zone of 1.5 m around the unit and a mini-
mum distance of 3 m at the unit’s exhaust opening are to be observed, even regarding non combustible objects.
The unit’s exhaust opening may not be reduced or
equipped with hoses or pipings.
Make sure not to introduce foreign matters into the
unit.
The air suction grille is always to be kept free from
dirt and loose objects.
The units may not be exposed to direct water jets. All electric cables outside the unit are to be protected
from damage (e.g. caused by animals, etc.).
Make sure to cut off the gas supply and to pull the
mains plug out of the mains socket when mainte­nance and repairs are carried out.
Description of Device
The unit is a mobile, liquid gas fired heater without a combustion chamber and with a fan for transporting hot air.
The unit works without an exhaust system and is only suitable for industrial purpose.
The unit is directly heated and are suitable for a all­purpose and simple application.
The unit are equipped with noiseless maintenance-free axial fan, durable gas burner, electromagnetic valve, piezo electric ignition, ignition protection with thermoe­lectric flame monitoring and connecting cable with plug.
The unit is in accordance with the basic safety and health requirements of the relevant EU – regulation.
Areas of Application
For drying new buildings. Spot heating of working places outside or in open, fire-
proof halls and production places.
Permanent or temporary heating of rooms with suffi-
cient fresh air intake.
For defrosting of machines, vehicles and non flam-
mable storage goods;
for tempering frost-endangered parts. Working of Device
When the unit has been switched on (operating switch in position "I" = heating operation), the supply air fan is started and the electromagnetic valve opens. However, the gas supply to the burner is still blocked.
The gas supply to the burner is released only after hav­ing pressed on the pin of the thermoelectric gas valve (safety pilot). The liquid gas is supplied by means of a nozzle under pressure to the burner pipe, where it is en­riched with an adequate quantity of oxygen which has been adapted to the burner capacity concerned.
The generated gas-air-mixture is ignited at the burner head by an electric ignition spark. The spark is gener­ated by the manual actuation of the piezo electric ig­niter.
The thermoelectric control of the flame is started by heating the thermocouple. The pin of the safety pilot is to be released.
Gas supply is interrupted in case of operating troubles or when the flame goes out. However, the supply air fan continues working. The unit has to be restarted.
The temperature limiter interrupts the gas intake when the unit is overheating. The automatic release of the temperature limiter occures after the unit has cooled down. A restart of the unit is necessary.
When any work is carried out on the gas supply line and when the gas cylinder is replaced, all stop valves must be closed and there may be no
G
ignition sources in the direct surroundings.

General Instructions
The unit may be operated only by those persons who
have been instructed regarding the unit’s operation and the handling of liquid gas.
When using the unit make sure always to ob-
serve the guiding principles of the countries and states concerned.
The unit may only be operated in rooms when
– the air rate fed to the unit is sufficient for combus-
tion and
– the rooms are well ventilated and de-ventilated
and
– the percentage of the substances which are injuri-
ous to health in the breathed in air has no inad­missible concentration.
A good and natural ventilation and deventilation
is given if e.g.
1. the room volume in m³ corresponds to at least 30 times the nominal heat load in kW of all the units being operated in the room, and if a natural air ex­change through doors and windows is ensured, or
2. if there are permanently open ventilation possibili­ties for ingoing and outgoing air near the ceiling and the floor, of which the size in m² corresponds to at least 0.003 times the nominal heat load in kW of all the units being operated in the room.
A uniform unit connection pressure of 0.3 bar (300
mbar) of category I
of the European Community.
The connection pressure may not fall below or ex-
ceed the required value.
When using longer hoses the corresponding pres-
sure loss has to be considered.
Make sure to use exclusively components, such as
gas hose, pressure controller and tube security de­vices (protection against breakage) or safety devices against gas leakage, that have been tested and are suitable for the intended purpose.
The pressure controllers must have a firmly regu-
lated initial pressure of 300 mbar and are to be equipped with a security device against tube break­age.
The unit may not be operated, if the gas occurs liq-
uid in to the burner.
is necessary for all countries
3B/P
In building site operation it is only allowed to use
hoses which are suitable for liquid gas. According to regional regulations.
The length of the gas hose should not exceed 2 me-
tres.
If there are special operational reasons and if corre-
sponding safety regulations are considered and the length of the hoses are as short as possible it is also possible to use longer hoses.
Gas hoses are to be protected generally against
chemical, thermal and mechanical damage.
In uncontrolled operation hoses with hose-break pro-
tection must be used.
The operating personnel has to check the function of
operation and safety devices and the existence of safety devices before starting the unit.
If any defects are stated the superintending person
has to be informed.
If any defect occurs which endangers the operating
security of the unit, the unit has to be switched off!
The unit may be only maintained by trained persons
and only original spare parts may be used.
Wearing and ageing parts of the unit have to be re-
placed regularly. This is not valid if an expert con­firms the faultless function of the unit.
If the unit has been switched off by the temperature
limiter due to overheating, the reason for the fault has to be detected and eliminated.
For optimum unit operation, the device should not be operated at an ambient temperature above 25 °C.

Before Starting
Make sure to charge a person with the operation of the unit and with the supervision of the reservoirs and of the bottle stock who has been instructed sufficiently regard­ing the handlings concerned.
Make sure to draw the operators‘ attention to possible dangers during the handling of liquid gas.
The persons charged with the operation of the units have to check the units before starting work to detect obvious defects on the operating and safety elements and to make sure that the safety devices have not been removed.
A constant unit connection pressure of 0.3 bar (300 mbar) must be ensured, also during continu-
G
ous operation.
When any work is carried out on the gas supply line and when the gas cylinder is replaced, all stop valves must be closed and there may be no
G
ignition sources in the direct surroundings.
Important information about the installation
When installing or removing the gas hose make sure to exert a counterpressure on the gas connection nipple of the unit using an open-end spanner SW 17 and observ­ing the left-handed thread.
This procedure also refers to all further gas compo­nents, such as pressure controller, hose security device (protection against breakage), etc.

Connection of gas supply
Make the connection as follows:
1. Connect pressure controller to the gas cylinder(s).
Attention! left-handed thread!
G
2. Open cylinder(s) valve(s).
When gas is taken out of sev­eral gas cylinders simultane­ously, all the valves have to be opened.
3. Press release button of the hose-break protection (protection against breakage) after having
opened the valve(s).
This has also to be done after each replacement of cylinders.
Insufficiently dimensioned supply plants can cause icing of the pressure gas or pressure reservoirs. When the gas pressure falls a proper gas supply to the consumer points can no longer be ensured in many cases.
This will result in imperfect combustion, harmful waste gases or extinction of the flame. Therefore the supply plant is to be dimensioned in such a way as to ensure that problems of this kind cannot be caused.
The crystalline white frost may not be removed by open fire, glowing objects or radiators.
Sufficient gas supply is to be ensured according to the unit power rating (see identification plate), service life and ambient temperature of the supply tanks.
In principle, we recommend that you use a set of at least 3 cylinders to avoid intensive icing of the reser­voirs. The number of cylinders can be increased by us­ing a set of several cylinders (accessories), depending on the unit capacity and the service life.
Assembly of Multi-cylinder Set
All cylinders valves must be open to ensure regular gas supply!
